Function Documentation

ltc2358_channel_data()

int32_t ltc2358_channel_data	(	struct ltc2358_dev *	dev,
		uint32_t	config_word,
		uint8_t	data_array[24],
		uint8_t	channel,
		uint32_t *	readval
	)

Read single channel data.

Parameters

dev	- Device handler.
config_word	- 24-bit config word created.
data_array	- 24 bytes of data from 8 channels.
channel	- Selected channel (0-7).
readval	- 3 bytes raw data for specific channel.

Returns

0 in case of success, negative error code otherwise.

ltc2358_create_config_word()

void ltc2358_create_config_word	(	uint8_t	channel,
		uint8_t	config_number,
		uint32_t *	config_word
	)

Create 24-bit configuration word for the 8 channels.

Parameters

channel	- Channel number.
config_number	- Configuration number for the channel.
config_word	- 24-bit config word created.

ltc2358_init()

int32_t ltc2358_init	(	struct ltc2358_dev **	device,
		struct ltc2358_init_param *	init_param
	)

Initialize the device.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

0 in case of success, -1 otherwise.

ltc2358_remove()

int32_t ltc2358_remove

(

struct ltc2358_dev *

dev

)

Free memory allocated by ltc2358_init().

Parameters

dev	- Device handler.

Returns

0 in case of success, -1 otherwise.
